BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a storage bag with a sealed zip capable of easily sealing or opening an opening of a bag for storing articles.

[0002]

2. Description of the Related Art A conventional storage bag with a sealed zip is made of polyethylene, which is formed on the inner peripheral surface of the opening of a storage bag for storing and storing articles, and is made of polyethylene like the recessed female section. And a male ridge which is press-fitted into the female female ridge to form a sealing zip in an opposed state. The outer peripheral surface of the opening of the storage bag body in which the female male ridge and the male male ridge are formed. The opening of the storage bag can be sealed by pressing the position with a finger to fit the concave female part and the convex male part, and the outer peripheral surface of the opening of the storage bag can be outside with both hands. It is configured so that the male convex portion can be inserted into and removed from the female female portion of the concave portion by pulling it to open the opening of the storage bag.

[0003]

However, since such a conventional storage bag with a closed zip has only one sealing strength of the closed zip, it is still inadequate in terms of completely storing the stored items. .

On the other hand, a concept has been proposed in which the sealing zips are formed in the front and rear two rows at the opening of the storage bag, so-called double zipper, to improve the sealing strength, but the sealing strength of the sealing zip itself is changed. Therefore, it was not the case that it exhibited a remarkable sealed state. It is an object of the present invention to improve such a conventional sealed zip and provide a storage bag with a sealed zip that exhibits an excellent sealing effect.

[0005]

The gist of the present invention will be described with reference to the accompanying drawings.

A zipper part A is formed by forming a female part 1 of a ridge and a male part 2 of a ridge which is press-fitted into the female part 1 of the ridge in an inner peripheral surface of an opening of a bag 4 for storing articles so as to face each other. Is formed into a shape having a predetermined vertical and horizontal width in the vicinity of the zip portion A on at least one inner peripheral surface of the facing inner peripheral surface of the opening of the storage bag body 4 and has an appropriate adhesive strength and is easy to The present invention relates to a storage bag with a sealed zip, characterized in that an adhesive layer 5 having an adhesive strength that can be peeled off is provided along the length direction of the zip portion A.

A plurality of zipped portions A are provided on the inner peripheral surface of the opening of the storage bag body 4 at predetermined intervals in the front-back direction when the opening side of the storage bag body 4 is the front part and the bottom side is the rear part. The adhesive layer 5 is formed in a row, and the adhesive layer 5 is provided between at least a pair of zip portions A on at least one inner peripheral surface of the opposed inner peripheral surfaces of the opening of the storage bag body 4. The present invention relates to the storage bag with the sealed zip described.

[0008]

Function: The outer peripheral surface on the outer side of the zipped portion A formed on the inner peripheral surface of the opening of the storage bag body 4 is pressed with a finger so that the concave female portion 1 and the convex male portion 2 are fitted together. The accommodating layer 5 formed in the vicinity of the zip portion A on one of the inner peripheral surfaces facing the opening can be adhered to the inner peripheral surface on the opposite side to seal the storage bag body 4.

When the outer peripheral surface of the opening of the storage bag 4 near the zip portion A is pulled outward with both hands, the male projection portion 2 is inserted into and removed from the female female portion 1 and the adhesive layer 5 is peeled off. The bag body 4 is opened.

[0010]

EXAMPLE This example is applied to a storage bag body 4 for various purposes such as a bag for storing food or a futon which is vacuum-sealed by using a suction device such as a vacuum cleaner. In the present embodiment, the recessed female portion 1 is formed on the inner peripheral surface of the opening of the storage bag body 4.
And the male ridge portion 2 are formed into two rows in the front and rear with a predetermined interval in the front-rear direction when the opening side of the storage bag 4 is the front side and the bottom side is the rear side. When the storage bag 4 is folded into a flat state, an adhesive layer 5 is provided between the front and rear zip portions A of one of the inner peripheral surfaces (upper inner surface and lower inner surface) of the opening facing each other. It is provided along the length direction of the portion A.

In the drawing, the base portion 6 is integrally connected to the entire circumference of the tip end of the opening of the storage bag body 4 by heat seal adhesion, and the zip portion A and the adhesive layer 5 are formed on the inner surface of the base portion 6 as described above.
The figure shows a case in which is provided on the inner peripheral surface of the opening of the storage bag body 4.

The concave female portion 1 and the convex male portion 2 are both made of polyethylene and formed by extrusion molding.

In the present embodiment, the left and right parts and the lower part when the male bottom 2 of the male ridge 2 on the inner surface of the female ridge 1 is the lower side and the male mouth 2 of the male ridge 2 is the upper side. There are three fine locking projections 3 provided along the length direction of the female recess 1 so as to be located at a total of three positions.

The locking projection 3 is preferably made of a flexible elastic material such as a silicon material or a soft urethane material (semi-hard urethane material), and any material may be used. In this embodiment, the locking convex strip 3 is formed together with the concave female part 1 by using a quick-hardening soft urethane material instead of a silicone material which takes several tens of hours from the molding to the curing.

In the case where any of the above-mentioned flexible elastic materials is used, the locking projection 3 is integrally formed by extrusion molding at the same time when the recessed female portion 1 is formed.

Therefore, the locking ridges 3 can be easily formed in the same manufacturing process as the conventional product. Further, in this embodiment, the locking ridges 3 are formed by using the soft urethane material, so that it can be completed in a short time. You will be able to do it.

The adhesive layer 5 of this embodiment is, for example, variously formed on a base paper wound around a rotating drum with a handle, and the dust is attached by rolling the drum on the floor surface. Is made of an adhesive soft urethane having an appropriate adhesiveness. With this adhesive layer 5 made of adhesive soft urethane, the width in the width direction of the storage bag 4 is made to match the width of the storage bag 4, and the vertical width in the depth direction of the storage bag 4 is several cm and the thickness is It is formed to a thickness of 0.5 mm so that it can be easily peeled off, yet it has a high adhesive strength, and it is formed so as not to impair the adhesive adhesion even if peeled off many times.

Further, it is desirable that the adhesive layer 5 is configured so as to extend widely between the front and rear zip portions A because the contact area of the inner peripheral surface of the opening portion when the storage bag body 4 is sealed is increased and the sealing strength is improved. . Since the adhesive layer 5 is also made of a soft urethane material like the locking ridges 3, it can be manufactured in a short time.

Therefore, in this embodiment having such a configuration, the opening of the storage bag body 4 is formed by the two front and rear rows of the zip portions A of the storage bag body 4 and the adhesive layer 5 between the front and rear zip portions A. Has a very high degree of tightness, and the opening of the storage bag 4 can be easily opened by pulling the outer peripheral surface of the opening of the storage bag 4 near the zip portion A outwardly with both hands. It becomes a very practical sealed zip.

Further, the left and right parts and the lower part when the fitting bottom side of the male ridge 2 is on the inner surface of the female female part 1 of the zip portion A and the insertion port side of the male ridge 2 is on the upper side Since there are three locking projections 3 having fine soft elasticity along the lengthwise direction of the recessed female part 1, the protrusions are formed on the female part 1 of the recessed line. When the male portion 2 is press-fitted, the locking ridge 3 comes into close contact with the male ridge 2 and the meandering gap between the female female ridge 1 and the male male ridge 2 is triple-blocked. It does not leak easily, and this triple blocking structure provides a very good degree of sealing.

Therefore, even when the liquid material is hermetically stored in the storage bag body 4, the liquid is unlikely to leak from the zip portion A.

The present invention is not limited to this embodiment. For example, a single zipped portion A is formed in the opening of the storage bag body 4, and the adhesive layer 5 is located closer to the tip of the opening than the zipped portion A.
May be provided, or three zip portions A may be formed and the adhesive layer 5 may be provided between the zip portions A.

Further, the adhesive layer 5 may be provided not only on one inner peripheral surface of the opening opposed inner peripheral surface of the storage bag 4 but on both opposed surfaces.

[0024]

Since the present invention is constructed as described above, the opening of the bag is firmly sealed by the zipped portion and the adhesive layer, so that the sealing strength can be kept extremely good and the adhesive layer can be easily formed. Since it can be peeled off, it can be easily sealed and opened as before, making it a very practical and productive sealed zip.

Further, the zipped portions are formed in a plurality of rows on the inner peripheral surface of the opening of the storage bag at predetermined intervals in the front-rear direction, and an adhesive layer is provided on the inner peripheral surface of the opening between the zipped portions. If so, the sealing strength is further improved.
